This trilogy was fun to read but I had a hard time giving it a rating. The first book was amazing and each author's style shined through and complimented each other.
The second book was ok but the third book took a huge leap that cheapened the entire trilogy a bit. But it's in the third book that you see how interwoven King's universe was in the entire story. It's a hard call but overall I really enjoyed the trilogy as a whole.
